X-men arcade (the 6 player x-men arcade game) [it would be awesome if up to 5 other random people could just notice me hosting this online and come join in any time or trade positions with others somehow.. or take over just like how groups of people really do at the actual arcade machine.]
Teenage Mutant Ninja Turtles arcade (4 player)

I always wanted to see all of these games with online play. I want them on PSVita and Nintendo Switch. I only really play portables these days.. or PC with steam or battle.net.

but dont bother if you cant give us "online multiplayer" because that is the whole point of me caring about these classics again.

oh yeah. "Real Bout Fatal Fury Special" would also be very cool to see. The first and part 2 are not as fun due to not being able to fight much in 2nd plain (background). And the extra destructible parts in environment. https://www.youtube.com/watch?v=Sk5T06qqeJ0&t=145s
